Answer:
g(x) = 4, 6, 9, 13.5 for the x-values given
Step-by-step explanation:
The table and graph are attached.
Answer:
3
Step-by-step explanation:
We know that 1 litre is equal to 1000ml (double the amount they're giving us), so 1 litre of paint is going to be $23 (we know this by multiplying 11.50 • 2).
Knowing this, all we need to do is multiply $23 • 4 which should give us $92.
So, the total of how much you will need to pay in this scenario to paint a room is $92 for 4 litres of blue paint.
Good luck!
Answer:
The numbers are 56, 280 and 156
Step-by-step explanation:
Let
x -----> the first number
y ----> the second number
z ----> the third number
we know that
y=5x -----> equation A
z=x+100 ----> equation B
x+y+z=492 ----> equation C
Solve the system of equations by substitution
substitute equation B and equation A in equation C and solve for x
x+5x+x+100=492
7x=492-100
7x=392
x=56
<u><em>Find the value of y</em></u>
y=5x -----> y=5(56)=280
<u><em>Find the value of z</em></u>
z=x+100 ----> z=56+100=156
therefore
The numbers are 56, 280 and 156
<em>Exterior angle of the triangle is equal to the sum of the opposite angles.</em>
9x = 5x + 9 + x
<em>Combine like terms:</em>
9x = 6x + 9
<em>Take away 6x from both sides:</em>
3x = 9
<em>Divide by 3 on both sides:</em>
x = 3
Answer: x = 3
